Series Is Presented Here As Two Variables--(1)--Original Data, 1921-1935 (2)--Original Data, 1935-1939 Data For 1921-1935 Were Derived By NBER By Adding Freight Steam Locomotive Miles To Departmental Miles, Subtracting Shunting By Freight Shunting Steam Engine-Miles, And Multiplying The Result By Pounds Of Coal Consumption By Freight Steam Locomotives (Including Departmental). During Processing It Was Discovered That Monthly And Quarterly Figures For 1931 As Provided By NBER Do Not Agree, But Data Have Not Been Changed. The Annual Figure Provided Here Was Computed From Monthly Data. Source: Computed By NBER From Ministry Of Transport Data In "Railway Statistics".

Use a formula to modify and combine data series into a single line. For example, invert an exchange rate a by using formula 1/a, or calculate the spread between 2 interest rates a and b by using formula a - b.

Use the assigned data series variables above (e.g. a, b, ...) together with operators {+, -, *, /, ^}, braces {(,)}, and constants {e.g. 2, 1.5} to create your own formula {e.g. 1/a, a-b, (a+b)/2, (a/(a+b+c))*100}. The default formula 'a' displays only the first data series added to this line. You may also add data series to this line before entering a formula.
